Be it known that I, HENRYKHYMAN, a citizen of thc UnitedStates, and residing at Brooklyn, New York,I county of Kings, have invented the new and useful Improvement in Battery Handlamps, of which the following is an specification.

This invention relates to battery hand lamps, andmore particularly to such lamps havingmetalcasings. The invention is also particularly adapted to that type of lamps having flared heads adapted to receive an enlarged ,lens and reflector.

One of the objects of this invention is to providey improved meansl for insulating and supporting the reflector, and positioning the same and the lampinI the casing;

Another object ofthis invention is to provide improved Ameans for receiving the thrust of the battery so as to relieve the lamp thereof. V i

Another object of this invention is to provide an improved construction for supporting, centering, and insulating the reflector which shall be simple and cheap to manufacture, and reliable in service.

Further objects will appear from the detail description taken in connection with the accompanying drawing, which represents a central vertical section of a hand lamp embodying this invention.

Referring to the accompanying drawing, 1 designates `the casing which, in the present case, is of metal and is provided with a shoulder 2 adjacent the lamp end thereof and a threaded portion 3v adapted to receive a corresponding threadedportion of a flared head 4.

Mounted within the casing 1 and vresting on the shoulder 2 is an insulating ring 5.'

This ring may be constructed of fibre or other suitable insulating material, and may be either solid or split at one portion of its circumferente so'as to provide a snug fit in the end of the casing. This ring extends Vfrom the shoulder 2 substantially to the upper end of the casing. y i L Mounted in the insulating ring 5 is a re. flector support comprising an insulating disc Li-adapted to rest at its rim uponv the upper edge of lthe ring 5 and having a central opening in which is mounted an eyelet or socket 7. Fixed to the disc 6 at kthe evelet 7 is a metallic cup 8 provided with a downwardly extending flange or rim 9. The rim 9 is Mounted onor integral with the socket 7i is an extension 10 provided near its lower end with an interna-l bead 11. Mounted in the extension 10 and resting against the bead p 11 is an insulating disc 12 retained in place by spinning over the edge 13 of the extension -or 1n any other suitable manner. The insulating disc 12 is provided with a central opening within which is mounted a c'up 14 adapted to contact with the central terminal 15 of the battery. Mounted within the cup 14 is another inverted cu y16 having an outturned flange 17 adapte to engage an inturned flange 18 on the cup 14 so as to prevent separation of the cups. 4Confined within the two cups is a spring 19 which tends to press the two cups apart. The cups 14 and 16 with their included spring 19 provide a yielding contact device connecting the central terminal of the lamp 20 with the battery terminal l5.

The reflector 21 is-providedr with the usual nipple 22 to receive the lamp 20 The reflector 21 is'mounted withits nipple 22 within the socket 7 so as to properly position the lamp 20 for, engagement with the yielding contactdevice 14-16.` This mounting also centers the reflector so that when its rim is .thumb-switch (not shown) on the casing to the rim 9,y lying betweeny saidA rim and the insulating ring 5 so as to provide .a circuit connection to that rim and tof the reflector.

The path of the current starting .from the lower'battery terminal lies through the casing which is in contact with said terminal, through the thumb-switch ,when closed, through the strip 23 to the rim 9, thence through the cup 8 to thefsocket t', thence through the reflector to the lam 20, through the lamp to the central termina thereof and thence through 'the yielding contact device .i6-i4 to the upper terminal 15 of the battery. Y, Y

When the reflector support has been assembledin the casing, it 1s retained in place by screwing down the rim 24 'formed on the head 4 so as to hold the support securely in place.
